erratic tach, battery/brake/seatbelt light help! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I did a search but i just want to confirm a few things to check today. My symptoms seem a little different than everyone elses.

since last week: key was stuck in ignition, buzzing from under dash above fuse box when i turn off car, finally got key out, battery/brake/seatbelt lights stays on

yesterday: seems egi relay is clicking, running a little shitty, key comes out all the time. still have buzz and lights when key comes out.

It seems that unlike everyone else, my brake/battery/seatbelt lights and the relay buzz only happens when i turn off the car and take the key out.

I added 2 engine grounds yesterday first off with no positive effects

no thoughts? i'm going to get the alternator tested because i've read that low amperage/voltage output will cause everything to go crazy

i was gonna say 99% its alt. i had same symptoms, your tach may be completely unrelated, check swap speed sensors or cluster or both

usually sign of the alternator going bad. I've had autozone test one and say it was still good, then had problems again the next day, then replaced it anyway and all problems were fixed. Think about all the electronics that need that constant power supply to work properly, everything mentioned by the OP guages, lights, seatbelts, egi.
